To'aL Zl whom it may concern: 7

Be it known thatI, ARTHUR J. Moxnan, a subject of the King of Great Brit ain, residin at VV'ilmin ton, county of Newcastle, an State of De aware, have invented a new and useful Improvement in Machines for Crimpi 1 ing or Bendin the Ends of Cylinders-Formed ofPlastic orFlexible Materialjnt'which the following is a full, clear,,and exact description, reference being had to the accompanymg drawings, which grin a part of this speci- .fication.

' M inventions ates to mac 'ne for crimping or bending the ends of similar material.

cylinders formed of plastic or flexible materialsuch, for instance, as the body portion of'kegs or vessels formed of pulp, paper, or It is the custom in this form of ke s or vessels to bend over or crimp the ends oi the body on the heads in order to secure or lock them in position. My ma-.

chine is especially adapted for this purpose.

In this class of kegs or vessels usually a body is first formed provided with an internal seat or projection near each end. A head is placed upon each of these projections, and the ends of the body beyond the projection are crimped or bent overupon or against the 1 surface of the respective heads.

I will first describe the embodiment of my invention illustrated in the accompanying drawings and then specifically point out the invention in the claims.

4. Fi 8 is a perspective view showing pawl 13 an its connection with slide 14.

a is'the frame of the machine, having the head 6, carrving the rotary spindle c, driven by the bevel-gear d, meshing with the bevelgear e on the shaft f, loose on which is the pulley g, the connection between pulley g and shaft being controlled by the cone-clutch h,

which is operated by the bell-crank '2', rod j,

lever is, pivoted at l, the lever being also connected to sprlng m. In an orifice upon a projection n from frame a is the rod or stand a new and useful" 1 ard 0, having the rack 19, which meshes with the pinion Q on the shaft 1'. On this shaft 2' l is the gear 8, meshing with the toothed sector t. The sector is on the shaft u, on which l is the lever L. w is the locking-pawl and the rack for said pawl. By moving the lever the standard 0 is elevated or depressed. .Car-

ried by this standard'is the platform y, upon which the keg is placed.

2 is a cylindrical shield which surrounds the keg or vessel and is formed in two parts hinged together and supported upon the rod' 40 and is locked in the closed position by the catches 41 42.

The crimping mechanism is secured to and rotated by the rotary spindle. Upon this spindle is the boss 3, having the counterbalance 4. This boss is provided with a radial groove in which rests the arm 5 and in which it is secured by the set-screw 6. On the under side of this arm is fitted the sector-frame 7, having on opposite sides the grooves 8 or guides 9. \Vorking in these guides is sectorslide 10. Upon each of the upper surfaces 06 this slide are the ratchet-teeth or racks 11 and 12, respectively.

13 is a pawl which engages the rack-teeth 11 This pawl is connectedto the slide 14 by means of the spring-piece 22. The slide 14 is fastened by a pin 15 to the lever 16, carrying on its upper end the roller 17. The lever 16 is fastened in a'pocket in the arm 5, in which it is secured by a pin 18. Contacting with this lever is the spring 19, fastened in the pocket by means of the screw 20. The slide 1% passes through the slide 21 on the arm 5 and carries on its outer end the springpiece 22, connecting it, the slide 14, and the pawl 13, which allows the pawl to lift out of the rack-teeth when the pawl is moved outwardly, and the slide 1-1 is moved a distance of a tooth when the pawl moves inwardly, The pawl 13 is moved outwardly by the action of the spring 19 and inwardly by the roller 17 in the revolution of the spindle, striking a lug 23, attached to the frame of the machine, and thus in each revolution of the wardly, advancing theslide the distance of a tooth.

On the boss 24 of the sector-frame is a pin 25, carrying the pawl 26, which is pressed tightly into the teeth of rack 12 by spring 27. This pawl is of such shape as to allow the sector-slide to move forward under the action of spindle .the pawl moves inwardly and outvessel.

pawl 13, but to hold the slide from backward movement. In order to release both pawls, and thusallow the slide to be brought to the extreme outward position, I secure to the pin 25-alever 28. Also connected to the pin is the trip 29, which is adapted to-contact with a pin. 30 on the pawl 26. The outer end of the lever 28 has in its line of movement a lug 31 on the pawl 13. When the lever-28 is operated, both pawls are released from engagement with their ratchets and the slide can be moved to the extreme outward position.

32 is the crimping-roller, which-is carried on the under face of the slide by means of the lug'33 and pin 34.

Pivoted upon the pin 35 on the arm 5 is the bifurcated oscillating hanger 36, which carries at its outer end, by means of the pin 37, the backing-roller 38. Secured to the sides of the hanger 36 are the springs 39 and 40, which at the other end are secured to the pin 41, carried by the arm 5. Through the lug 42 on the sector-slideis the pin 43. When the sector slide advances inwardly sufliciently, it will strike the oscillating hanger 36, and further inward movement will lift the hanger and backing-roller out of the path of the crimping-roller.

The operation of the machine is as follows: The vessel is placed on the platform; the shield closed around it. The shield does not extend the entire height of the vessel, and it is the portion above the shieldthat is to be crimped. The sector-slide is moved into the position shown in Fig. 1. The platform is elevated until the vessel assumes the position shown in Fig. 4. and dotted lines, Fig. 5, the backing-roller being within and the crim ing-roller without the vessel. The spindle is then rotated, which carries the crimpingroller and backing-roller around the vessel, acting upon the upper surface of the vessel. In each rotation the slide is rocked inward, carrying the crimping-roller, and thus forcing the surface of the vessel farther inward. When in the movement of the slide the pin strikes the backing-roller oscillating hanger, it is swung so as to carry the roller out of the This enables the slide in'its further movement to complete the crimping. When the crimping of one end of the vessel has been completed, it is lowered, the vessel reversed,

and a like operation performed in the other end. The vessel is then moved and a. new vessel acted on.
